I actually have triplet cousins (born in 1990). They we're conceived naturally, but my aunt has a few instances of twins in her family. They're two boys and a girl (JessicaKate, SamAlexander and ThomasMitchell). Sam was quite developmentally delayed as a child, but is totally fine now. They were born prematurely, but I'm not sure how premature, given that I was only six at the time. I should probably ask my mum! By the way, when you're six, having baby triplet cousins is so much fun! Probably less fun for my aunt and uncle

So am I. I've only ever known two instances of triplets in my entire life: three girls who were a good few years below me in primary school, but everyone knew them because they were all identical (or at least appeared to be, I don't know for sure as I was only 10 or 11 at the time) and a friend of my sister's, who has two triplet brothers. Twins, I run out of fingers to count on how many I've known over the years, but triplets (and higher multiples) are far rarer.
